A remove.bg alternative for simple cutouts

On this device, backdrop removal flood-fills a flat color from the corners and stops if the cut would eat the subject. The cloud tool uses BiRefNet (MIT), not BRIA RMBG. Hair and glass can still be wrong.

Use it for a sweep, a paper background, or a simple icon. Do not use it for hair, glass, or a street. There is no public API for it yet. The developers page says what a future API would and would not cover.
